Misleading Achievement Title

A Line In The Storm IV:Guide Maelstrom to 100 frontline victories.
Clear as day.

Behind Enemy Lines: Guide any of the three Grand Companies to a total off 200 Frontline victories combined.

Misleading you added the worlds total and combined but you also said guide any of the three. Now I can confirm if you change Gc's only you first Gc counts so if you get 180 wins and decide to change which my friend did you've stopped her from obtaining the Ads and she can't switch back to obtain ads now either because of the stupid wait so many earth days crap.

Make the information to obtain it more clear by saying" Win 200 games as one grand company" Not as any or combined.

She has won 200 games total but now stuck at 180 wins because of misleading requirements

I second this. From personal experience I have done the same thing and it is very frustrating.
